Title: ( d , n ) proton-transfer reactions on Be 9 ,  B 11 ,  C 13 ,  N 14 , 15 , and F 19 and spectroscopic factors at E d = 16 MeV

Abstract

The (d,n) reaction has been studied with targets of 9Be, 11B, 13C, 14,15N, and 19F at Ed = 16MeV using a deuterated liquid-scintillator array. Advanced spectral unfolding techniques with accurately measured scintillator response functions were employed to extract neutron energy spectra without the need for long-path neutron time-of-flight. An analysis of the proton-transfer data at forward angles to the ground states of the final nuclei, using finite-range distorted-wave Born approximation analysis with common bound-state, global, and local optical-model parameter sets, yields a set of self-consistent spectroscopic factors. These are compared with the results of several previous time-of-flight measurements, most done many years ago for individual nuclei at lower energy and often analyzed using zero-range transfer codes. In contrast to some of the earlier published data, our data generally compare well with simple shell-model predictions, with little evidence for uniform quenching (reduction from shell-model values) that has previously been reported from analysis of nucleon knock-out reactions. Data for low-lying excited states in 14N from 13C(d,n) also is analyzed and spectroscopic information relevant to nuclear astrophysics obtained. Here, a preliminary study of the radioactive ion beam induced reaction 7Be(d,n), E(7Be) = 30MeV was carried out and indicates further improvements are needed formore » such measurements, which require detection of neutrons with En < 2MeV.« less
